05.563GPPCTS-Fixed Part (FP) radio subsystemGSM Cordless Telephony System (CTS), Phase 1TS
The CTS-FP shall fulfil all the requirements in the full voltage range, i.e. the voltage range between the extreme voltages.
The manufacturer shall declare the lower and higher extreme voltages and the approximate shut‑down voltage.
0,9 * nominal
1,1 * nominal
Outside this voltage range the CTS-FP, if powered on, shall not make ineffective use of the radio frequency spectrum. In no case shall the CTS-FP exceed the output power levels as defined in GSM 05.56 for extreme operation. In particular, the CTS-FP shall inhibit all RF transmissions when the power supply voltage is below the manufacturer declared shut‑down voltage.
